Application filed January 29, 1913, Serial f 4 ,'I'QaZ'lello/m,'ttm/(1yconcern.v

llc it known that pl, Russnnn R. VVn'rnn- MAN, a citizen oit the United States, and a resident ot' San Diego, in thecountypt San Diego and rState of California, have invented certain new and useful Improvements 1n Bags, ci' tion. i

.My inventiony relates to an attachment adapted to iieep the' gas pressure uniform when the gas expands and contracts in dirigible balloons or gas bags and to keep the gas evenly distributed therein by means of netting` in connection with a u'indlass, and the principal objects of lny invention are, first, to provide van attachment that will make aerial navigation safer, second, to provide an attachment that will facilitate the controlling of said dirigible balloon or gas bag, third, to provide an attachment that can be attached to any dirigible balloon or gas bag, fourth, to provide such an attachment that is simple of construction, durable, automatically operated and easily attached, fifth, to provide an attachment that is positive in its action, und sixth, to in?,

.ivhich the following is a specificalVith these rand other objects in view as will hereinafter appear, my invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the` characters of reference thereon, which form a part of this specification, in which:-

Figure l is a transverse sectional view of my attachment complete shown in connection with a dirigible balloon, andFig. 2 is a side elevational view thereof on a smaller scale. i

Similar characters of refe-rence refer `to similar parts throughout the several views. ln the drawings, numeral 1 represents the gas bag, 2 the ordinary netting, 3 the at. t-achment netting, 4 the auxiliary take .u cables, 5 the main take up cables, 6 the pu leys, 7 auxiliary idler pulleys, 8 the main idler pulleys, 9 the Windlass and 10 the car. The gas bag l is an ordinary gas bag or` dirigible balloon lwhich is covered with an Specification of Letters Patent.

vdrum of the windlass $2 principles, construction an Ordinary meshed netting To this netting rammed July 1.4, 1914,

No. 744,865. Renewed May 28, 1911i.y Serial No.,841,667'. y

2, on each side of the bag is attached aiplu;

rality of pulleys 6, which are located as".

shown best in Figsjl and 2, and are rigidly secured to said "meshed'netting by means of crow-looting. Suspended a short distance.

below the gas bag the pendant 10 is secured by means of the extended ends of the netting 2. l,The attachment v, meshed netting 1s similar to netting 2, but covers only` the ortionof the bagLat the bottom not covered .and it` is held in ythe ordinary nettin? p a' auxiliary take up ce; lay a plurality j o cables t which are rigidly fastenedcn'feac 1 side ofithe netting 3 "at its top edge und are each provided with the prevent the bag from expanding, thus caus' mg the strain tov be on secured, This Win'dlass 9 consists of u; drum 9a which is provided onone end `with a small drum 9* the brackets 9 lower ends to the bottom of the pendantlO. A cable 9d is rigidly fastened tothe small drum 9b and is wound arounda number of times, then secured to the tension spring 9 which is rigidly secured to the' floor of said pendant 10.

and is pivotally mounted 'on Though I have shown vand-described a particular construction and arrangement I do not Wish to be 'limited to 'this particular stops 5N which will the netting .3 and. not on the ba Said auxiliary cables arev around the pulleys 6then, v

7 and rigidly faswhich are secured at their,

8 anddcwn tothe on which they are construction anderrangeinent, but 'desire to Y include in the purview of substantially as set fort-h in the -appended claims.

- t is obvious that With .this construction` there is provided an attachment that -will prevent a gas bag from 'becoming Hubby,

by the evaporation ores@4 i pas therefrom, by meansoflthe,

together byfmeans ci?I the windings Q9, thus;`

m ,linventiontheY 2 arrangement keeping the gas in said dirigiole balloon 0r gas bag evenly con'iprcssed and .preventing it .from moving fro o one portion of said gas or dirigible balloon to another, and, as a result, that it will malte aerial navigation saler; that it will `facilitate the controllingV 'of said dirigilile balloonsor gas bags; that said attachment can be readily attached to any dirigible balloon or'gas bag; thaty it is durable and automatic in its action.'

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is Lf ln an attachment for gas bags of 'the class described, the combination of a nett-ing tain tension.

ln an attachment for dirigible balloons, the combination of :1 netting stretched over the vlower surface of` said dirigible balloon, a pin ali tyl of pulleys mounted along the 03o-, posite sides of said balloon, a plurality el cables attached to the sides of said netting extending over said pulleys provided""\vith :stops whereby sale; cables are prevented from traveling too far on said pulleys 1n either direction, a drum mounted in thel car upon. which said cables arewound, another cable wound on said drum, and a spring attached to said. Litter mentioned cable-'for holding said net at a certain tension against the lower surface ofrsavid dirigible balloon.v

from' the edges of said netting, a plurality l ot cables attached to thesides of' said 1iettingpassino over said pulleys and a spring regulated darum upon which the other ends of said cables vare Wound.

4. A device of the class described comprising a netti'n adapted to tit over the lower surface ot a gas bag, a plurality of pulleys attached to the netting on each. side of said gasfbag', av plurality ol.' cables attaehed to thefsides-o said netting and paesing over said pulleys provided with stops in said cables for preventing l said cables from passing 4lhrougli said pulleys after they have reached acertain position, a Aplurality of idler pulleys for said 'cables and adapted for guiding them to the v.positions desired, a drum mounted in the car of the dirigible `balloon u )on which the ends 0I" said cables are wenn and a spring'means in connection ywith said drum for holding said cables in a certain tension at all times.

In witness whereof, l have hereunto subscribed my name inthe presence of two subscribing Witnesses. .y
